TELEPHONE CALL=REGISTER.

SPECIFICATION forming part of Letters Patent No. 259,428, dated June 13,1882.

Application filed October .22, 1881. (No model.)

To all whom it may concern Be it known that 1, JAMES SEE, ot' Hamilton,Butler county, Ohio, have invented certain new and useful Improvementsin Telephone Toll Systems and Apparatus, of which the followingis aspecification.

For the purposes of identification among other specifications oftelephone toll systems and apparatus invented by myself and by othersjointly with me, I designate this as the specification of Case No. 3.

This invention relates to systems andappara-tus for indicating theamount of toll due from users of telephone-lines.

IS The accompanying drawing illustrates the system and apparatusinvolved ata station or premises of a telephone user.

A is a common magneto call device, having usual bells, t, crank C, andpush-button E.

S is the telephone, connected as usual. M is the line entering the calldevice, as usual, and departing to ground or continued line at N 0.

There is nothing uncommon about the devices thus far referred to, exceptthat the ob- 2 structing-pin D prevents the complete or continuousrotation of the crank C. The crank can be turned nearly a fullrevolution and then back again, and so on; but it cannot be turnedcontinuously. The lack of continuity 0 in the signal thus produced givesto the sig-- nal sent from such a device a distinctive characteristiceasily distinguishable from a continuous signal. This distinctive signalis not to be recognized by the central officc as a call, 5 and isaccordingly not answered. This signal is used answering calls receivedand for ringing 01f after the user is done with the telephone.

B is a signaling device similar to A, F being 40 the crank, G theobstructive pin in the path of the crank, and J the push-button. Thesignal sent by the device B would be identical with the one sent by Awere it not for the fact that the obstructive pin G moves out of the 5path of the crank F each time the button J is pressed. The system ofrods and levers by which this is accomplished is clearly shown in thedrawing, and it is obvious that the pin G may be connected with thebutton J in other ways, so as to still produce the desired effect.

It will readily be seen that the calling device B may at any time beused to send over the line a continuous uninterrupted signal to berecognized and answered by the central OflIlCE. I is a counter orregister, which indicates each time the button J is pressed.

It will readily be seen that the indicator I will count the calls sentto the central office, and thatanswering and ringing ot't' are notcounted.

if it is desired to guard against a user fastening the button J in itsupward position, and thus being at all times in readiness to send callswithout actuating the counter I, such guarding may be accomplished in anobvious manner by causing the button J to act as telephoneswitch, whichmust be in its downward position to permit the telephone to be used.

For instance, let the wire P be the connection between the two deviceswhen the button J is up and the wire N the connection when the button isdown. It is obvious that the upward position of the button J tends toshortcut the circuit and render the device A, with itstelephone,inoperative. The arrangement of such circuits and switches iscommon and requires no explanation here.

The devices A and B- are illustrated as two separate structuresconnected by conductors N or N and P; but itis obvious that both may becombined in one structure and the parts utilized for double duty withoutthe exercise of invention. For instance, the device A may be constructedwithout any button E, as is often donein signaling devices. This permitsthe interru 'ited signal to be sent by simply turning the crank C, andno button need be manipulated. If the device 13 be arranged in a similarmanner-that is to say, in such manner that answering signals may be sentwithout manipulating a button-it is obvious that the device 13 wouldanswer for both answers and calls, the calling-button J being used andthe counter I accordingly actuated each time the call is sent. 5

The object of the invention is to count each call sent to the centraloffice, and at the same time permit a telephone user to answer calls andto ring off without actuating the counter, in order that toll-chargesmay be based on calls sent by the user only. The system is apat astation on a line, of a calling device hav- 1o plicable to forms ofsignal devices other than ing aregister or counter attached, and anancrank machines. Thus a system of batteryswering' and ringing-oftdevice independent of signaling may be used, and the button which saidregister or counter, substantially as and actuates the counter mayactuate the callingfor the purpose specified.
